FDS Express - FREE - unlimited users with no clustering - 1 CPU ( multi-core supported )
The number of users on FDS Express is tied to the scalability of the server. Most machines fail in supporting a high number of concurrent users at the host operating system. Some OS's are more scalable than others. FDS Express is wide open to allow developers to build great things on a single CPU (multi-core supported). The problem is that once your service becomes valuable and mission critical you need to support redundancy in terms of failover and clustering. This is the point at which a commercial FDS license makes sense. Do you want to build business critical apps on a single point of failure? The commercial licenses of FDS provide J2EE scalability and clustering support. It allows large companies to build much larger more scalable solutions as follows: FDS Express - FREE - unlimited users with no clustering - 1 CPU (multi-core supported) FDS Departmental - $6K per CPU - 100 concurrent users across cluster - multiple CPU support - clustering support FDS Enterprise - $20K per CPU - unlimited users across cluster - multiple CPU support - clustering support At the same time the FDS Express license allows developers to create great applications that leverage a single server. When your service needs mission critical scalability and performance, there are licenses to support those needs. Jack, the bits between FDS versions are identical. A commercial license turns on clustering support and there are no errors in your application on the 101st user. Hope that helps clear some FUD on FDS.
